SYNOPSIS

PARAMETERS

Address of the read-write lock object whose object name is to be obtained.
Location to store the obtained object name.
Length in bytes of buffer at the location specified by name.

DESCRIPTION

This routine copies the object name from the read-write lock object
specified by rwlock to the buffer at the location name. Before
calling this routine, your program must allocate the buffer indicated by
name.

The object name is a C language string and provides an identifier that is
meaningful to a person debugging a DECthreads-based multithreaded
application. The maximum number of characters in the object name is 31.

If the specified read-write lock object has not been previously set with an
object name, this routine copies a C language null string into the buffer at
location name.

RETURN VALUES

If an error condition occurs, this routine returns an integer value indicating
the type of error. Possible return values are as follows:
Successful completion.
The value specified by rwlock is invalid.
